Patented July 8, 1930 UNITED STATES PATENT OFFICE JULIUS DORNE'II-I, OFBERLIN-KONRADSI-IOHE, GERMANY, ASSIGNOR TO THE FIRMTYPOGRAPH-GESELLSCHAFT M. B. ZFL, F BERLIN, GERMANY MATRIX-SETTING ANDTYPE-LINE-CASTING MACHINE Application filed April 23, 1929, Serial No.357,480, and in Germany November 13, 1928.

In matrix setting and type casting machines with ring spacers, thelatter have a given diameter so that in the case of the usual heights ofline, they close the casting slot of the casting mold as indicated inFigure 3 of the accompanying drawing. If however particularly high linesare to be cast, these space rings are not sufiicient, as a tight closingcan be obtained with them only if they are advanced to the extent a asindicated in Figure 4: of the accompanying drawing. This is however notpossible in existing machines. In such cases special straight spacerstherefore are used which have to be inserted by hand.

According to this invention the square spindle which carries the spacerings is resiliently mounted, and thus it is possible to use theordinary ring spaces contained in the machine, for any height of line.The result of this mounting by means of springs is that the space ringsautomatically assume the positions shown in Figures 3 and 4, as well asany intermediate positions that may be required.

A construction according to the invention is illustrated in theaccompanying drawing, applied to a machine in which two space rings aremounted one above the other on a 3 bar suspended to a guide wire.

' Figure 1 is a cross section.

Figure 2 is a plan.

Fig. 3 is a fragmentary elevational detail partly in section showing theposition assumed by the ring.

Fig. 4 is a similar view showing the same parts in another position. I

Two space rings 7) are arranged one above the other on a bar 0 and areheld in the setting position by square spindles ol'which are mounted atboth ends in supports 6, f. The

supports are provided with guide blocks 9 which are adjustably mountedin guides h by means of a pin h and slot k The blocks 9 and therefor thesquare spindles are always held by means of springs c in such a positionthat the space rings can freely run on to them the said rings being thenin the position advanced (in Figure 4) to the extent a, so that a tightclosing is ensured even when high lines are cast. If ordinary lines areto be cast, the casting mold support is will force back the space ringswith the parts 03, e, f, g, to the extent a, so that the space ringswill be brought into the position according to Figure 3 in which a tightclosing will also take place.

Having now particularly described and ascertained the nature of the saidinvention, and in what manner the same is to be performed, I declarethat what I claim is 1. In a matrix setting and type line castingmachine a casting mold, ring spacers, a square spindle carrying the saidring spacers in the line, supports at both ends of the said spindle,guides for said supports and springs located in said guides and actingon the supports. I

2. In a matrix setting and type line casting machine, a casting mold,ring spacers, a square spindle carrying the said ring spacers in theline, springs supporting the square spindle against the pressure of thecasting mold and allowing a vertical movement of the said square spindlein relation to the 7 said casting mold.

In testimony whereof I afiix my signature.

JULIUS DORNETH.
